.SPECIFICATION forming part of Letters Patent No. 699,291, dated May 6, 1902. Application filed November 9,1901. Serial No'811673- (Nt model.)

.To all Awhom t may'concern:

Be it known that I, CHARLES E. DE LoNG;a citizen-of the United States, residing at the city of Hot Springs, county of Garland, State 5 of Arkansas, have invented a certain new and 'ro part of this specification.

This invention relates to single-trigger lock mechanisms for double-barrel guns; and it has for its object to provide means for limiting the movements of the trigger as it is maa5 nipulated for firing the gun and to improve the means for preventing the unintentional ring of the second barrel by reason of the in- I voluntary pullupon the trigger which takes place immediately upon the firing of the first 2o barrel.

I have illustrated an embodiment of my invention by the accompanying drawings, in which- Figure lis a side View of the lock mechan- 2'5 ism, showing the parts in the position they assume when the gunis cocked. Fig. 2 is asimilar view showing the position of the parts af- `ter the first barrel has been fired. Fig. 3 shows the parts in position for iiring `the sec- 3o ond barrel, and Fig. Il illustrates the same parts after' the firing of the second barrel. Fig. 5 is a plan view of the parts shown in the other views. Fig. 6 is asecticn on the line 6 6 of Fig. 5.

The gun-lock mechanism illustrated in the common need not be described in detail.

Referring to the drawings, A indicates the 4o frame; B, the barrels; E E, the sears, and G the trigger, which is provided with a plate Gf, secured to its heel or rear portion and which willbe describedi detail hereinafter. These parts in the accompanying drawings are represented as comprising parts of a double-barrel hammerless breakdown sporting gun. Some of the parts usually present in thelock of such a gun-fas, for instance, the safety device-are not shown, as they form no part 5 -o my present'invention and the omission tends to clearness of illustration of those parts in which my invention is embodied.

The trigger is preferably situated between the two sears, and in an aperture in the plate G' thereof there is mounted a shiftabie searcontact Z, provided with a finger-piense', projecting lthrough the frame in convenient position for manipulation. Accordingly as the nger-piece .is moved the contact Z will lie under the right or the left hand sear, so that upon the first pull of the trigger that barrel will be fired whose Sear is raised. In order to fire 'the' other barre1, Imake use of what I term a stepping sear-oontroller-that is, a device which at different stages in the manipnlation of the mechanism occupies different -steps or positions, the last step or position being such as will Vcause afiring of the secondA barrel upon the trigger being pulled. N indicates this stepping Sear-controller, and O a spring which engages therewith and tends to move it forward. It rests upon two'lugs or posts secured to the frame A, its forward end upon the luga and its rear portion upon the lug n.4. The rear under portion of the searcontroller N is shaped to form two steps or shoulders n n', and the forward of these, n, is adapted to engage with the rear upper edge of the lug 0.4 and so retain the scar-controller in a retracted position.

The plate G of the trigger is provided with a heel or projection g, which is arranged to engage with the Sear-'controller and raise it vas the trigger is pulled. This heel portion of the trigger is preferably situated a little back of the lug a4, audits upper edge lies a little `Toeiow the upper edge of the lug 'when the trigger is in its lowermost or forward position. The stepping scar-controller is provided with a pair of hooks or catches y, disposed one on each side of the Sear-controller and arranged to engage with the sears E whenlthe controller is moved forward, but to be freev therefrom at other times.

The trigg -plate Gr' is' provided with pins 95 or projections arranged tolie under the,

ends of the hooks when the scar-controller is Y pose of loading-as, for instance, the bolt R.

When it is thus moved back, the shoulder or step n engages the edge of the lug c and holds the scar-controller in its rearmost position.

If `now the trigger be pulled, the barrel under whose sear the contact-piece Z may be situated will be red, and at the same time the rear portion of the Sear-controller will be lifted from engagement with the lug and will be moved forwarda short distance ,by the spring O into the vposition indicated in Fig. 2, with the'step n engaging with the rear upper edge of the heelg of the trigger and with the shoulder n above the top of the lug a4. If now the pressure upon the trigger be released and it move downward under the infiuence of the trigger-spring, the parts will assume the position shown in Fig. 3, the heelof the trigger having disengaged the step n and the searcontroller having been moved forward by its spring O into position to fire the second barrel. This will carry the hooks y under the sears, so that the next pull of the trigger will, through the Sear-controller, the hook, and the Sear of the unfired barrel, result in a firing of the second barrel.

In order to prevent the unintentional firing of the second barrel by the involuntary pull upon the trigger, I combine with'the scar-controller a retardin g device similar to that shown in my Patent No. 690,243, dated December 31, 1901.

915 represents a pawl connected with the rear end of the scar-controller and arranged to engage with a'ratchet-wheel p, mounted upon a shaft supported in the lug a. Upon this shaft is mounted a spur-wheel p', which engages with a spur-pinion 1)". Upon the same shaft with the pinion p there is mounted an escapement-wheel 19"', with which there engages a vibrating escapement drag pawl p". A spring 'ne holds the pawl 'a5 in engagement with the ratchet-wheel. The parts of this escapement mechanism are very light and capable of rapid operation; but they nevertheless operate to retard the forward movement of the Sear-controllersuiciently to permit the involuntary pull to take place beforethe searcontroller arrives at such a forward position as to permit the firing of the second barrel. As this mechanism is fully described in my aforesaid application, its operation and functions need not be further described herein.

I have also invented a means for preventing an undue movement or draw-of the trigger upon the firing of the first barrel and also for preventing the trigger from falling under the influence of the' trigger-spring (which is not herein shown) after the firing of the first barrel and before the second barrel is fired.

WV represents a lever pivotcd to the frame `O forced forward.

h and arrangedwith its upper end 1n position to engage with the rear end or portion of the.

scar-controller. It is provided with a slot w, of peculiar. construction,into which a pin V, carried by the trigger-plate, is adapted to enter. A spring U, having bearing against a stationary part of the mechanism, as the lug et, tends to swing the lever in a forward direction. Vhen the gun is cocked and in position for firing, the parts occupy the position shown in Fig. 1, with the sear controller locked in its rearmost position, the trigger dqwn, and the lever W forced backward by reason of the engagement of the scar-controller with its upper end. When the parts are thus positioned, the piu V lies outside the slot w and just below the open end thereof. The pull of the trigger, which results in firing .the first barrel, brings the parts to the position indicated in Fig. 2. The scar-controller by this pull of the trigger is forced upward, so that the. shoulder or step n is released from the lug f and the controller is by the spring trigger-plate, is at the same time moved upward, and the spring U ilii'rces the lever W forward, the pin moving over 'the inclined face 2 at the entrance of the slot w. Before the pin fully enters-the slot, however, its movement, and consequently the movement,

of the trigger, is arrested by the pin coming into engagement with the shoulder 3, situated at the entrance to the slot w at the upper edge thereof. This device prevents any overdraw of the trigger, allowing it to be moved just far enough'to operate the scar and iire the first barrel. After the first barrel has been fired and as the trigger is released in order to fire the second barrel the lever W is forced still farther forward and comes to the position indicated in Fig. 3, where it rests upon a shoulder 4 at the lower end of the slot. The engagement of the pin with this shoulder operates to arrest the downward movement of the trigger, holding it in such position that but a short pull is required to re the second barrel. The pull which results in firing the second barrel carries the pin into the upper portion of the slot, as indicated in Fig. 4f.

When the gun is broken for discharging the shells and reloading, the Sear-controller is moved backward,and it in turn moves backward the lever W, restoring the parts to the position shown in Fig. 1.
